Somebody please tell whats wrong with my 2001 GTP i live in Northern Utah and travel down to RMR maybe once a month. I just did a bunch of work this spring and my car runs like crap down the track but awesome up here. my mods include block bored .20 over, XP cam, balancer shaft removed, OE-R 875 lifters, #105 springs and retainers, powerlog headers, ported SC and ported lower intake. ported TB. and a some what cold air intake (warm air intake) it doesnt go down the fender like it should. and 3.2 pulley. And a tune on the PCM. the problem im having is i cant break 15.0 seconds to save my life, its driving me crazy everyone i talk to say i should be in the low 14.0 high 13.0. Please dont quote me on that the first of the season i had bald radial tires and a 3.4 pulley and i ran 14.8 all day. Thank you for all your opinions you might have for me.
